Hi all
I am in process to upgrade ESXI 4 AND ESX4 TO ESXI 5.0
But before starting just I have a few question.
Environment 1
ESX4.1 linked with EMC storage - HA enabled
Environment 2
ESXI4.1 Linked with Hitachi storage- HA enabled
1-is there any issue if I upgrade while the disks are online or I should disable them.
2- Is there any points should I consider before upgrading from ESX TO ESXI.
